INGANDESCENT-LIGHT GUARD.

Specification of Letters Yatent.

Patented Feb. 23, 1915.

Application filed April 27, 1914. Serial No. 834,679.

To all whom it may concern Be it known that I, CHARLES FRANK RUBIN, acitizen of the United States, and resident of Milwaukee, in the countyof Milwaukee and State of Wisconsin, have invented certain new anduseful Improvements in Incandescent-Light Guards; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof.

My invention consists in what is herein particularly set forth withreference to the accompanying drawings and pointed out in the claims ofthis specification, its object being to provide simple, economical andefiicient guards for the protection of incandescent electric-lights,upon which they are self adherent.

Figure l of the drawings represents an elevation partly in section of aguard in accordance with my invention applied to an incandescentelectric-light bulb that is shown by dotted lines, and Fig. 2, a planview of the guard partly in horizontal section on the plane indicated byline 22 in Fig. 1.

Referring by numerals to the drawings, 3 indicates a ring, 3 an outerflange of the ring, 4,- each of a series of curvilinear bars and 5 asocket, the bars being at regular intervals apart and connecting saidring and socket to therewith form a cage of approximate hemisphericalform. Spot-welded or otherwise rigidly secured to the flange 3' of thecage-ring 3, in register with the bars of said cage or otherwise, areoutwardly bent ends of a series of fiat spring-arms 6, the free ends ofthese arms being inwardly converging and preferably forked as hereinshown. If forked, the free end of each spring-arm is bent upon an arc ofa circle.

The cage is preferably fashioned from a single circular blank ofsheet-metal, but its construction, and the application of thespring-arms thereto, may be indefinitely varied without departure frommy invention, as herein claimed.

The cage with the spring-arms extending therefrom constitute a guard inaccordance with my invention, and this guard being slipped on anincandescent electric-light bulb, the nib of the bulb comes within thesocket-end of said cage, while at the same time there is a spread of thefree ends of said arms to effect a grip of the same on said bulb. Hencethe guard as a whole is self adherent on the bulb.

In practice, the guards will be made in various sizes corresponding tostandard sizes of incandescent electric-light bulbs.

I claim:

1. An incandescent light guard comprising a cage consisting of a ringhaving an outwardly extending flange, a socket with which to engage thenib of the light-bulb, and curvilinear bars at regular intervals apartconnecting the ring and socket; together with a series of inwardlyconverging spring-arms each having an end thereof in rigid connectionwith the ring-flange of the cage.

2. An incandescent light guard comprising a cage consisting of a ring, asocket with which to engage the nib of the light-bulb, and curvilinearbars connecting the ring and socket; together with spring bulb-grippingdevices in rigid connection with said ring of the ca e.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee in the county of Milwaukee and State of Wisconsin in thepresence of two witnesses.

CHARLES FRANK RUBIN.
